We're seeing performance gains of up to 2x for this release in Ambient Occlusion lighting. LightUp uses a stratified Hammersley sampling and for this release we rolled in Importance Sampling - which simply means we focus on the areas that contribute the most to your image.

Also new in this release is upgrades to the realtime shadow rendering to improve the sharpness of the shadows on larger models. v5.0 adds Cascaded Shadow Maps (CSM) which allow us to focus shadow resolution on the areas that need it most.
